The stem flow of spruce and larch had acidulation on the soil, but the soil around the bole of spruce didn't present intensive acidity (the lowest pH of water and KCl immersion were 5.13 and 4.79, respectively), so the acidulation of stem flow is not the direct reason of spruce death.

虽然两树种树干径流对土壤均产生了酸化作用，但由于云杉树干周围土壤PH并没有出现较强的酸性（水浸pH下降到5.13，盐浸pH下降到4.79），因此，还不能认为云杉的衰退死亡与树干径流的酸化作用有直接关系。

Models for the electromagnetic interaction between the target and trunks or between the trunks and trunks are developed, and these models are used to derive the coherent fields scattered by the target and fractal forest. Then, the polarization angular correlation function is calculated by using azimuthal angular averaging, and used to detection target buried in forest.

I staid by it to load my Gun, and then coming away I could easily see the Thieves sitting upon all the Trees about me, as if they only waited till I was gone away, and the Event proved it to be so; for as I walk'd off as if I was gone, I was no sooner out of their sight, but they dropt down one by one into the Corn again.

我做木板的方法是这样的：因为我需要一块较宽的木板，就选定一棵大树把它砍倒。砍树花了三天的时间，再花了两天把树枝削掉，这样树干就成了一根大木头，或者说是成了木材。然后用大量的时间慢慢劈削，把树干两边一点点地削平。

介绍了各种热技术测定树干边材液流的基本原理和方法，并对热技术在树干水分运输格局、影响和调节树干边材液流的内外因素、基于树干液流测定值推算林分冠层导度和尺度放大以及夜间树干液流等方面研究中的具体应用进行了综述。

The analysis shows that vertical growth is achieved thanks to discrete contact points and regions with continuous contact, that the contact pressure creates tension in the stem as observed experimentally, and that there is a maximal radius of the pole around which a twiner can climb.

这个模型可以解释为什么藤蔓不能在半径大于一定值的树干上生长，他们计算出当树干半径大于3.3倍的藤蔓自然曲率半径时，藤的尖端便不能继续缠绕树干向上生长，而是自身卷曲起来。文章的后一页半研究了摩擦力的影响，很明显，摩擦力是使藤蔓植物能够支撑自身重量的主要原因。

The results are as follows:The relationship between the precipitation and the stemflow is a linear regression. The stemflow of six forest types is Broadleaf forest, Conifer and broadleaf forest, Cupressus funebris forest, Mixed conifer forest, Pinus massoniana forest and Shrubbery and grass land in order.

结果如下：树干茎流量与降雨量成线性相关，回归方程达到极显著水平；6种森林类型的树干茎流量从大到小依次为阔叶林、针阔混交林、柏木林、针叶混交林、马尾松林和灌草地；不同树种间的树干茎流量差异极显著，影响树干茎流量的主要树体特征因子是冠型结构、胸径和平均冠幅。

Fire resistance of Pinus armandii bole were tested with fuel bed designed by the authors during the prohibitive period of forest fire. The mortality rate was accounted with a program developed by the authors with Visual Basic 6.0 after the phloem of samples were soaked with 4% 2, 3, 5-triphenyltetrazolium chloride solutions, then painted and scanned the distributing map of mortal and living phloem, purified the map color with Photoshop. Relationships between fire resistance of the bole and diameter, wood bark thickness, temperature, and heating time were anayzed. Countermeasures of forest fire protection were put forward.

在森林防火戒严期，用自行设计的装置对云南主要造林树种华山松进行了不同温度、时间作用下的树干耐火性试验，用红四氮唑对高温作用后的树干韧皮部进行了染色，经勾绘、扫描后用Photoshop软件将死亡的韧皮部处理成易于计算机识别的纯色，用Visual Basic 6.0编写的程序计算了树干韧皮部的死亡率，初步分析了华山松树干耐火性率与树干直径、树皮厚度、受热温度、受热时间的关系，据此提出了相应的森林消防措施。

Results showed that the topsoil (10cm) pH increased with increasing distance from bole. The minimum topsoil pH presented on the region of bole base. Some contour lines of topsoil pH were concentric circles which centered in boles.

结果表明，两树种树干周围表层土壤(10cm)的pH均由树干基部向外围逐渐增加，pH最低值常出现在树干基部附近，有的树干周围土壤pH等值线呈近似同心圆的分布。

目前，在运用各种热技术对林木树干液流的研究中，树干水分运输格局还需借助其他手段和方法进一步准确测定和佐证；影响树木边材液流内外因素的协同和补偿作用还需系统研究；基于热技术测定的树干液流值进行耗水时空尺度的扩大将成为该领域的研究热点之一。

As they went, Robin's men hewed down great poles from the forest trees, which they took with them, and, fifty yards from the gate of St. Mary's Abbey, they set up a gallows of these poles, and on it hanged Roger the Cruel, with the Abbot's parchment of promise sewn on his breast, that all men might see. Across the foot of it Friar Tuck had written at Robin's bidding:"This doom to Abbot Hugo's hireling murderer. When next Abbot Hugo goes abroad, the doom will find him too."

当他们走时，罗宾的人从森林的树砍下树干，他们带着树干，距离圣玛利亚寺门口五十码时，他们用这些树干架起绞台，上面吊着残酷的罗格，修道院院长答应的羊皮纸挂在他的胸部，所有的人都可看见，距离一尺之处，塔克修道士写下罗宾的命令：「这是雨果修道院院长雇用谋杀者的命运，下次雨果修道院院长外出，这样的命运也将会捕捉到他。
